Multi-layer Belt Food Drying Machine

DW-series Belt Food Drying Machine Introduction

DW-series belt food drying machine with multi-layer is a continuous convective drying processor of which the drying of the product takes place on ventilated conveyor belts. The food drying machine is widely applied for mass production of continuous drying for sheet, strip pellet material with better ventilation property, especially for the materials that cannot bear high temperature such as dehydrated vegetables, Chinese herbal pieces of high moisture content. Amisy belt drying machine is produced by the professional development engineers based on many years practical experience. Likehot air drying oven and microwave drying machine, the belt food drying machine is also popular in the market.

Distinctive Features of Mesh Belt Food Drying Machine

1. Special multi-layer belt design can make the materials heated uniformly and continuously which highly improve the drying efficiency.
2. The time of material staying on the belt and velocity of feeding material can be adjusted in order to obtain the best drying effect.
3. Hot air can be circularly applied, the energy is greatly saved.
4. Large capacity, high drying and thermal efficiency.
5. Low energy consumption, easy to operate and maintain.
6. Wide utilization range, many kinds of materials can be dried such as fruit and vegetable drying, traditional Chinese medicinal materials drying, food drying, industrial drying and etc..

Main Structure of DW-series Belt Food Drying Machine

This belt drying machine includes the following main parts：drying room, feeder, heat exchanger, circulating fan, circulation blower, control valve, belts and some other accessories.

Working Principles of Food Dryer

After the wet material is evenly fed onto the top layer of drying belt via the belt conveyor feeding system, the moving drying belt transports the wet material to the other end and drop onto the beneath the layer of drying belt. The beneath drying belt then transports the wet material and moves in opposite direction until dropping onto the third layer of drying belt. At the same time, hot air is evenly blown into the dryer via the bottom air distributor. With the help of exhaust fan, the hot air penetrates the wet material on each layer of drying belt for heat transfer and take away the evaporated moisture. When the material reaches the bottom drying belt, it is dried for discharging.
